kompaktilamput

Kompaktilamput, also known as compact fluorescent lamps (CFLs), are a type of energy-efficient lighting designed to replace incandescent bulbs. They work by passing an electric current through a tube containing argon gas and a small amount of mercury vapor. This generates invisible ultraviolet (UV) light, which then strikes a fluorescent coating on the inside of the tube, causing it to emit visible light. Early versions often had a warm, yellowish light, but modern CFLs are available in a range of color temperatures, from warm white to cool daylight.

The primary advantage of kompaktilamput is their significantly lower energy consumption compared to traditional incandescent bulbs. They use about 75% less electricity to produce the same amount of light and have a much longer lifespan, often lasting 6,000 to 15,000 hours, compared to the 1,000 hours of an incandescent bulb. This longevity translates to reduced replacement frequency and further energy savings.

Despite their advantages, CFLs have some drawbacks. They contain a small amount of mercury, which requires careful disposal to prevent environmental contamination. They also take a short time to reach full brightness after being switched on, and their light quality may not be as desirable as newer LED technology for some applications. The dimming capabilities of CFLs can also be inconsistent depending on the specific model. While still in use, their market share has been decreasing as LED technology offers further improvements in energy efficiency, lifespan, and light quality.
